helmets, such as disclosed in my prior United States Letters Patent, No. 1,931,339.

In hair drying devices of this type, which are now in general use, the heated air, after acting upon the head, discharges into the room which is an undesirable feature, particularly in warm weather and warm climates, as obviously, it effects a substantial increase in the room temperature. Air conditioning systems for cooling the air are now being contemplated and installed in beauty parlors and other similar establishments where hair dryers are used, so as to in part, counteract this undesirable feature, 20 and it has been estimated that it will require one-third of a ton of refrigeration to counteract the amount of heat dischargedfrom a single hood during its average daily use. 1

The invention therefore broadly comprehends an improved hair drying apparatus including means communicating with the head receiving space of each helmet which functions to convey away and discharge outside of the room the heated air after the same has acted upon the head in order to avoid the raising of the room temperature, while, at the same time, making for a more rapid and efficient drying operation by continuously carrying away the moisture laden air from the head receiving space and thereby making way for the incoming fresh air. The invention also provides, in an apparatus of this character, a distensible conduit leading from the hot air duct to the helmet, which conduit consists of telescopically adjustable sections with an improved means for automatically retaining said sections in relativeadjusted posi-' tion against accidental or unintentional move-' construction and mode of operation, which may be produced economically and which is highly efllcient for its intended purpose.

With the above enumerated and other objects an improved hair drying apparatus of the-specified type, which is comparatively simple in its in view, reference is made to the following specification and accompanying drawings in which there is set forth -a preferred embodiment of the invention, while the claims cover variations and modifications thereof falling within 5 the scope of the'invention.

'In the drawings! Fig. 1 is afragmentary front view of a multiple hair drying apparatus.

Fig. 2 is an enlarged fragmentary vertical 10 sectional view through one of the helmets and the ducts.

Fig. 3 is a view similar to Fig. 2, illustrating the lower section of the distensible conduit in its uppermost position to cut oif the supply of 5 hot air to the helmet.

Fig. 4 is a horizontal sectional view taken approximately on the line 44 of Fig. 2.

In the drawings, A designates a common air heating and blower unit having an outlet B com- 20 municating with a hot air supply duct or manifold 0 leading therefrom and preferably extending horizontally and located overhead. The duct or manifold C has connected thereto, communicating therewith, and depending there- 25 from, conduits, designated generally by the reference character D, which communicate at their lower ends with dryer hoods or helmets, generally designated by the reference character E. Each conduit D consists of upper and 30 lower telescopically associated tubular sections [0 and II, the former being provided at its upper end with a semi-spherical flange l2 which is mounted for universal movement between spaced semi-spherical flanges i3 secured to the 35 duct or manifold C and framing the outlet opening l4 thereof. This provides a connection between the duct or manifold C and the conduit D which permits of limited universal swinging movement of the conduits with reference to the 40 duct or manifold, while establishing communication therebetween. The lower section II of the conduit D, which is telescopically slidable with reference tothe head of the patron. 55

The hood er helmet n which is substantially of the conventional type, includes inner and outer 1o dome-shaped walls as and 2i which are connected at their marginal edges at 22 and spaced apart throughout the remainder of their areas to provide an air chamber 28 communicating with the lower end of the section H of the con- 15 duit B through an opening 26 formed centrally oi the outer wall 2E. The inner wall 2c of the head or helmet E is provided, with perforations as constituting hot air outlets distributed over the area of the head receiving space 26 formed -20.by the concavity defined by the inner wall 20.

The inner wall '20 is formed with a, central outlet opening 21 connected with a vent conduit, designated generally by the reference character F, and which conduit preferably extends centrally 25 upward through the supply conduit D, and is of lesser, diameter than the conduit D to provide a hot air supply passage between the conduits. The vent conduit F includes telescopically associated upper and lower sections 28 and 29, the 3 former having a flexible section 30 in the region of the universal joint between the supply duct or manifold C and the supply conduit D.. The vent conduit F-extends upwardly through the duct or V manifold C and communicates with a superposed 35 vent manifold 3|. The upper portion 32 of the vent conduit F, lying between the flexible portion 3a and the vent manifold 3 I is rigid and supports an annular horizontally disposed'fiange 33 which constitutes an abutment and closure for the upper 40 end of the lower section II of the supply conduit D when the lower section is moved to its uppermost position. When in this position, communication between the hot air supply duct or manitold C and the section II of the supply duct D 45 is cut off so that the operator automatically shuts oi! the flow of hot air to the hood by merely rais- -ing-the hood or hgelmet to the limit of its movement. A valve 34' may be located in the vent conduit F for cutting off or regulating communi o cation between the same and the vent manifold 3|, if it is desired to permit the hot air to be discharged from the hood or helmet into the.

room.

The vent manifold 3| is connected withan 55 outlet which discharges outside of the room G V and a suction may be created therein either by natural draft from a stock or by means of a suction fan 35. r

What is claimed is: 1. In a hair drying apparatus, a helmet adapted to recei ve the head and having walls defining an air distribution chamber and openings through one of said walls for distributing air from said chamber to the head, a hot air sup- 65 ply duct and a distensible conduit leading from the duct to the distributing chamber of the helmet, said duct comprising telescopically asso ciated tubular sections,means connecting one of said sections to the duct for universal 7o movement with reference thereto, one or said sections being provided with a peripheral groove in confronting relation to the other section, and a resilient split ring arranged between said sections within said groove to frictionally retain the sections in relative adjusted position while permitting oi the manual telescopic sliding of the sections. a

2. In a hair drying apparatus, a helmet ada, ted to receive the head and having inner and outer walls defining an air distribution chamber and/openings through the inner wall for distributing air from said chamber to the head, a hot air supply duct, a vent duct, a distensible hot air conduit comprising telescopically associated tubular sections, one of said sections being rigidly aihxed to the outer wall of the helmet, means of connection between .the other section and the hot air supply duct to permit of relative winging movement of said latter-section with respect to said duct; and a distensible vent conduit located within the hot air conduit comprising telescopically emaciated tubular sections, one

of said sections being rigidly ailixed to and opening through the inner wall of the helmet. and the other of said sections being connected to the vent duct.

3. In a hair drying apparatus, a helmet adapted to receive the head and having inner and outer walls defining an air distribution chamber and openings through the inner walls for distributing air from said chamber to the head, .a hot air supply duct, a vent duct, 9. distensible hot air conduit comprising telescopically associated tubular sections, one of said sections being rigidly affixed to the outer wall of the helmet, means of connection between the other section and the hot air supply duct to permit of relative swinging movement of the latter-section with respect to said duct; a distensible vent conduit located within the hot air conduit comprising telescopically associated tubular sections, one oi. said sections being rigidly aflixed to and' opening through the inner wall of the helmet and the other of said sections being connected to the vent duct, and means located between the sections of the hot air conduit for automatically retaining both of said conduits in relative adjusted position, while permitting of the manual telescopic sliding movement of the sections.

4. In a. hair drying apparatus, a helmet adapted to receive the head and having inner and outer walls defining an air distribution chamber and openings through the inner wall for distributing air from said chamber to the head, a hot air supp y duct, a vent duct, a distensible supply conduit comprising upper and lower telescopically associated tubularsections, the lower section being rigidly aflixed to the outer wall of the helmet, the upper section being connected to the hot air supply duct, a distensible vent conduit located within the supply conduit comprising upper and lower telescopically associated tubular sections, the lower section being rigidly afflxed to and opening throughthe inner wall of the helmet and the upper section being connected to the vent duct, and means on said latter sec-'- tion with which the upper end of the lower section of the supply conduit is adapted to engage for cutting on the hot air supply to the helmet.
